United States Patent M BABY CRIB STRUCTURE John J. Kedrowski, Stevens Point, Wis. Application December 2, 1955, Serial No. 550,689

2 Claims. (Cl. -63) This invention relates to the class of furniture and more particularly to a novel baby crib.

The primary object of the present invention resides in the provision of a baby crib structure which employs means for raising and lowering the bottom member or mattress of the baby crib when one of the side members thereof is lowered for permitting access to the baby in the crib while the bottom member is lowered when the side member is raised to. thus provide maximum protection for the baby.

An additional object of the invention resides in the provision of means for holding a side member of a crib in a vertically adjusted position while also holding the bottom member or mattress of the crib in.a vertically adjusted position.

An additional object of the invention resides in the provision of a baby crib structure which has means mounted underneath the bottom or mattress thereof so as to be out of the way and not engageable by the hands or limbs of a baby, which means functions so that when a side member is raised, the bottom member is lowered, and when the side member is lowered, the bottom member is raised.

The construction of this invention features novel guides carried by the end members of the cribs on which the side members are mounted. One of the side members is vertically adjustably mounted on a pair of the guides and has a pitman pivotally attached thereto which pitman is rigidly connected to gear means which are connected by a link arrangement to the bottom member.

Still further objects and features of this invention reside in the provision of a baby crib structure that is strong and durable, simple in construction and operation, efiicient in use, and inexpensive to manufacture thereby permitting wide distribution and utilization.

These, together with the various ancillary objects and features of the invention which will become apparent as the following description proceeds, are attained by this baby crib structure, a preferred embodiment of which has been illustrated in the accompanying drawings, by way of example only, wherein:

With continuing reference to the accompanying drawings wherein like reference numerals designate similar parts throughout the various views, reference numeral 10 generally designates the baby crib structure comprising the present invention. This baby crib includes a pair of end members 12 and 14 which may be provided with legs or casters as may be desired.

Mounted'on each of the end members 12 and 14 are pairs of substantially L-shaped upper brackets 16 and 18 through which pairs of vertical guides as at 20, 22, 24 extend. A pair of lower L-shaped brackets 26, 28 are mounted on the end members 12 and 14 respectively at one side thereof. Anchoring means as at 30 and 32 provide means for holding the guides 20 and 22 in position and may be in the form of a washer and a cotter key, as shown, or such as other means as desired. Intermediate L-shaped brackets 34 and 36 are positioned directly above the brackets 26 and 28 and the guides 20 and 22 extend therethrough. 1

Arranged in the same vertical level as the brackets 3.4 and 36 and on the opposite side of the end members 12 and 14 therefrom as can be seen best in Figures 3 and 5 are a pair of brackets 38 through which the guides as at 24 extend. Another L-shaped anchor bracket 40 is at-- tached to each of the side members 12 and 14 directly below the brackets 38 and spaced a short distance therefrom. Vertically slidably adjustably mounted on the vertical guides 20, 22 and 24 are a pair of spaced angle members 48and 50 which together with angle members or the like as at 52 and 54 form a bottom member frame for a mattress support which may be of the spring mounted type as indicated at 56, or such other arrangement as may be desired whereby a mattress as at 58, see Figure 2, may be readily supported.

In order to limit the uppermost position of the bottom member with respect to the vertical guides, stops as at 58 are mounted on the vertical guides and these stops may each comprise U-shaped plates 60 together with clips 62 which hold the plates in a selected position.

The vertical guides 20 and 22 are each provided with a series of notches as at 64 and 66 respectively therein. Side members 70 and 72 are provided, the side member 72 being rigidly held in an upper position since the lower rung 74 of the side mernbers 70 is held in a positive manner between the brackets 38 and 40. The side frame member 72 is vertically slidably adjustably mounted on the guides 20 and 22 and the upper rung 78 thereof is slotted at each end thereof as at 80 for reception of latch plates 82 which are adapted to engage in the notches 64 and 66. An operating cam 84 is provided for each of the latch plates 82 and a spring 86 urges the latch plate 82 into a locked position. Suitable screws 88 extend through slots 98 in the latch plate for limiting the movement of the latch plate 82 and for reinforcing the assembly. The operating cam is pinned as at 92. Hence, when the operating cam 84 on each side of the upper rung 78 of the side member 72 is actuated compressing spring 86, the latch plate 82 is withdrawn from the respective notches 64 and 66 allowing vertical adjustment of the side member 72.

The side member 72 has a pair of substantially L-shaped brackets 94, see Figures 3 and 5, to which a pair of links 96 are pivotally attached as at 98. Pitmans i 100 are pivotally attached as at 102 to the links 96 and are rigidly afiixed to a firstpair of wheels 104 the teeth 6 of which are interenga ged with the teeth 108 ofthe pair of'wheels 1'10.

7 Each of the tooth wheels 194 and 110 are rotatably :mounted on the end members 12 and 14 by means of shafts 112 and 114 respectively and are held'in place by .stop plates 116 as well as by cotter keys.

Rigidly affixed to the tooth wheels 104 and 110 are pairs of arms 117 and 118 which are pivotally attached as at 120 and 122 to links 124 and 126 carrying stub shafts 128 and 130 respectively whichfit into suitable notches'in the angle member 50. Hence, when the side member 72 is lowered from the position as is shown inf-Figure 3 to the position as is shown in Figure 4, the tooth wheels 104 and 110 are revolved causing the arms 117 and 118 toibe rotated thus raising the bottom member'and the mattress. Of course, the latch plates 82 engage in the notches 64 and 66in the guides 20 and ;22 and s'erveto hold the side member in a selected position as well as holding the mattress in the coiresponding selected position. Hence, when the side member is in the lowered position as is shown in Figure 5, access mayfbehad to the baby in a raised position on the mattress. However, in order to safeguard the baby when the "baby is left'in its crib, it is merely necessary to raise the side member 72 at which time the mattress is lowered.

An'inspection of Figure 9 will illustrate the constructionof the brackets such as the brackets 26 and 28 uti- "lizedfor mounting the guides. It is noted that the guides .such as the guide 22 is notched as at 140 and is adapted Ito seat in a slot 142 in the bracket 28. The bracket f28'is provided with screw apertures as at 144 allowing the bracket to be secured by any convenient fastener to the end member 14. A clip 146 similar to the clip :62is positioned on the vertical guide 22 and is apertured as at 148. The clip is provided with a flanged portion'150 for engagement in a resilient manner with the edge 152 of the bracket 28 and the undersurface 'thereofso that the clip will serve to hold and lock the guide 22 in a selected vertical position with respect to the bracket.

The foregoing isconsidered as illustrative onlyof the principles of the invention. Further, since numerous 4' modifications and changes will readily occur to those skilled'in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:
